Dragon Disciple

[Eristophenes]

One of my players has problems with Dragon Disciple and his attacks. DD gets claw attacks and bite. What if he wants to attack with normal weapon and claw... I assume that there are normal penalties according to fighting with two weapons (and claw is a light weapon)... What about attacking with weapon and the bite? Or claw and the bite? MM says that you get your bite attack at your max attack bonus and claw attacks at -5.
I know that mu thread is maybe a little bit chaotic, but what I want to know is:

1. What are the modifiers for fighting with weapon and the bite?

2. What are the modifiers for fighting with weapon and the claw?

3. What are the modifiers for fighting with bite and the claw?

4. Is it possible to fight with weapon, claw and bite in the same round? What would be the modifiers?

Thx
